MACHINE FOR MAKING HEEL-RANDS.

SPECIFICATION formingpart Of Letters Patent NO. 724,700, dated April 7, 1903.

v Application filed December 31, 1902. Serial No. 137,244. (No model.)

To all whom ifmay' concern:

Be it known that I, AMASA OfHEAT of make its shape permanent and give it the desired uniformity of cross-section throughout its entire 1ength;and it consists in certain, improvements hereinafter described and claimed on a machine of this character set forth in Letters Patent of the United States No. 587,283, dated July 27, 1897.

Of the accompanying drawings, forming a part of this specification, Figure 1 represents a side elevation of a rand-machine embodying my improvements. Fig. 2 represents a plan view of the same. Fig. 3 represents a section on line 3 3 of Fig. 2. Fig. 4 represents a front elevation of the blank guiding and pressing head and the blank-bending formers. Fig. 5 represents a View similar to Fig. 4, showing the position of the formers after their bend ing movement. Fig. 6 represents a section on line 6 6 of Fig. 5. Fig. 7 represents a side elevation of the portion of the machine shown in Figs. 4 and 5, the formers bein'gin the position shown in Fig. 4. Figs. 8 and 9 repre sent views similar to Fig. 7 showing the positions of the formers at difierent stages of the operation. Fig. 10 represents a perspective view of a completed rand. Fig. 11 represents a perspective view of a rand attached to a heel-lift.

The same reference characters indicate the same parts in all the figures.

In the drawings, a represents a head, which is a stout metal plateaflixed to a supportingframe (1 and having a flat surface at one side.

I) b 1) represent sections collectively formin gapresser-foot. Said sections are movable toward and from the head a, means being employed for normally pressing the presser-foot sections toward the head and permitting them to yield therefrom. The presser-foot sections codperate wit h the head a, in supporting a rand-blank c, interposed between said sections and head, while the formers,hereinafter described, are heading the blank into heel shape, the yielding pressure of the sections toward the head causing said head and sections to grasp the blank and hold it at any point to which it may be moved by the formers, so that the blank is caused to conform closely to the contour of the inner edges of the formers, as will be presently explained.

(1 represents a heel-shaped follower, which is mounted upon a slided, Fig. 2, movable in guides d on the supporting-frame a and is provided with operating mechanism whereby itis moved toward and from the head a, said operating mechanism having provisions for holding the follower d stationary at difierentpoints, first, when the follower is separated from the head a to afiord room between the head and follower for the bending of the blank and the formation of corrugations on its inner edge, the corrugations being the result of" the bending of the blank, and, sec ondly, when the follower has been moved up to the head a to flatten out the corrugations of the-blank and complete the rand, the said mechanism being also adapted to move the follower backwardly a sufficient distance to permit the.comn1eted rand to drop from between the head and the follower.

The mechanism for giving the follower the described movements comprises a lever (1 mounted to oscillate on a fixed stud d rods 0Z connecting the levers d with the ends of a stud 0Z projecting from opposite sides of the follower-supporting slide d, and a cam 01 affixed to the driving-shaft and formed to first move the follower from its extreme rearward position partly, but not entirely, to its pressing position and to then move the follower.

to its pressing position. The fulcrum d of the lever d is so arranged that the entire weight of the lever is exerted to hold a trundle-roll d on the lever in contact with the cam d ,so that when the cam permits the lever to swing downwardly the weight of the lever acts to retract the follower. Y

The presser-foot section bis affixed to a shank b which is adapted to slide in a guide 11 affixed to the slide d, and is normally pressed forward with the section b by a spring 0. The sections b b are provided with shanks b movable in guides on the slide (1 and pressed forward by springs b. The form of the sections bl) b in side elevation is shown by dotted lines in Fig. 5, from which it will be seen that the three sections collectively form a presser-foot which extends over the top and along the sides of the follower d, their inner edges conforming to the curvature of the follower. The independence of said sections and the means for pressing them yieldingly toward the head Ct enables the sections to bear closely against all portions of a rand-blank inserted between the sections and the head a.

The presser-foot sections are retracted with the follower by the contact of projections on the shanks of the sections with suitable parts moving with the follower. For instance, the shank l) has a stud 12 which abuts against one end of a slot in the guide b while the shank b has a collar which abuts against the guide for said shank. The springs b and I) press the presser-foot sections forward when the follower is retracted, as shown in Figs. 1 and 3, so that the sections project slightly in advance of the acting face of the follower, the sections yielding when they come in contact with the rand-blank c.

e e represent a pair of formers which I term secondary formers to distinguish them from the primary: former, hereinafter described. Said secondary formers are movable upon the flat face of the head a and have curved inner edges, which collectively correspond to the outline of the side portions of the follower d and are adapted to bend a rand-blank a into heel form, as indicated in Fig. 5. The formers e e are afiixed to carriers e e, which are formed upon hubs or sleeves e 6 mounted to oscillate upon studs 6 e which are affixed to a primary slide a. Said slide is movable between guides at a, formed on the head a. Said primary slide has an offset portion 8 projecting over the upper end of the head Ct, said upper end constituting a stop e against which the lower end of the portion 6 abuts, said stop limiting the downward movement of the primary slide. To the offset portion or projection e is affixed an intermediate or primary former e", which is located between the secondary formers e e and has a curved lower end ar ranged to bear on the central portion of the rand-blank, as shown in Fig. 5, when the slide 6 is depressed, said intermediate former cooperating with the head a and the central presser-footsectiou bin partially bending and holding the central portion of the rand-blank before the end portions of the blank are bent by the secondary formers.

e represents a secondary slide which is located below the primary slide and moved between the guides a, and is provided with studs 6 e to which are pivotally connected two links or connecting-rods e 6 the upper ends of which are pivotally connected to the former-' carriers (2' e. The secondary slide 6 is reciprocated in the guides a by a mechanism hereinat'ter described, and during the first part of its downward movement from the position shown in Figs. land 7 it imparts a like movement to the primary slide a through the links e until the projection e strikes the head a, when the movement of the primary slide is arrested. This movement of the primary slide depresses the former-carriers a without swinging them on their pivots, thus carrying the formers from the position shown in Figs. 4 and 7 to that shown in Fig. 8 and causing the primary former e to bear on the central portion of the blank 0 and bringing the secondary formers into close proximity to the end portions of the blank, the central portion of the blank being forced by the primary former downwardly between the presser-foot section b and the head a. The downward movement of the secondary slide continues and is caused, through the links e e", to swing the former-carriers and the secondary formers downwardly, as shown in Figs. 5 and 9, the secondary formers being thus caused to complete the bending of the blank into heel form and to force its end portions between the side sections b of the presser-foot and the head a. The pressure to which the blank is subjected between the presser-foot sections and the head sufficiently retards the movement of the blank to cause it to conform accurately to the shape of the curved edges of the primary and secondary formers. The mechanism here shown for reciprocating the secondary slide e is a lever 6 pivotally connected to the supporting-frame at e, a cam e on the driving-shaft s, and a weight e suspended from an arm e, fixed to the lever 6 said lever having a trundle-roll e on one of its arms arranged to bear upon the cam 6 The other arm of the lever e is connected by a link e with an ear 8, formed on the secondary slide a. The lever e is oscillated vertically by the conjoint action of the cam and weight and imparts a vertical reciprocating motion through the link t' to the secondary slide e The operation is as follows: Assuming the follower d to be at rest in the position shown in Fig. 3, a rand-blank c, which is tapering in cross-section, its outer edge being comparatively thick, while its inner edge is very thin, is placed below the formers and between the central presser-foot section Z) and the head, the blank being heldin this position by frictional contact with the said section and head. The secondary slide e is then depressed and depresses the primary slide e through the links (2 until the downward movement of the primary slide is arrested by the- .the secondary formers to swing downwardly,

as shown in Figs. 5 and 9, and thus complete the bending of the blank into heel form. The

bending operation corrugates the inner edge a of the blank, the space between the head and the follower being sufficiently wide to permit the free and regular formation of the corrugations. The follower next advances against the head a and flattens the corrugations, thus making the-bent form of the blank permanent and finishing the rand, the acting face of the follower being beveled to give the desired bevel to the upper surface of the rand. The follower is then retracted, carrying with it the presser-foot, the follower and foot being thus removed from the head sufficiently to permit the completed rand to drop through an opening in the supporting-frame.

To permit an independent yielding movement of the follower 01 when it is acting on the rand and thus compensate for variations in the thickness of different rands, I provide the followerwith a shank d Fig. 3, which is adapted to move endwise in a guide (1", formed on the slide d. Said shank is backed by a relatively stiff spring, preferably composed of a series of cupped resilient washers d surrounding a rod (Z afiixed to and extending rearwardly from the shank (1 said spring being interposed between a nut d engaged with the shank, and an adjustable abutment (Z engaged with an ear (1 formed on the slide (1'. The nut (Z limits the forward movement of the follower by the spring d and the adjustable abutment 01 enables thepressure of the spring to be varied. The adj ustable abutment d and stop-nut (1 enable the forward movement of the follower to be arrested at any desired distance from the head at, so that the machine can readily be adjusted to permit a heel-lift c, Fig. 11, to be placed against the head a in position to have the bent blank or rand pressed against it by the follower, one side of the blank or the outer surface of the lift, or both, having been previously coated with cement to cause the adhesion of the rand to the lift.

The head a is preferably provided with a block a of yielding elastic material, such as vulcanized rubber, said block being inserted in a recess formed for its reception in the head. The elasticblock a is formed and arranged to sustain the pressure of the crown or extreme outward bulge of the acting face of the pressercl and act as'an auxiliary to the spring d in preventing such injury to any of the parts as might result if the block a were not provided.
